Accounting Policies [Abstract]
Summary of Significant Accounting Principles	Summary of Significant Accounting Principles Bank of America Corporation, a bank holding company and a financial holding company, provides a diverse range of financial services and products throughout the U.S. and in certain international markets. The term “the Corporation” as used herein may refer to Bank of America Corporation, individually, Bank of America Corporation and its subsidiaries, or certain of Bank of America Corporation’s subsidiaries or affiliates. Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition, and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing, and the Corporation’s proportionate share of income or loss is included in other income. The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could materially differ from those estimates and assumptions. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. The nature of the Corporation’s business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results, have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission. Certain prior-period amounts have been reclassified to conform to current period presentation. New Accounting Standards Reference Rate Reform In March 2020, the FASB issued a new accounting standard related to contracts or hedging relationships that reference LIBOR or other reference rates that are expected to be discontinued due to reference rate reform. The new standard provides for optional expedients and other guidance regarding the accounting related to modifications of contracts, hedging relationships and other transactions affected by reference rate reform. The Corporation has elected to retrospectively adopt the new standard as of January 1, 2020 which resulted in no immediate impact. While reference rate reform is not expected to have a material accounting impact on the Corporation’s consolidated financial position or results of operations, the standard will ease the administrative burden in accounting for the future effects of reference rate reform. Accounting for Financial Instruments -- Credit Losses On January 1, 2020, the Corporation adopted the new accounting standard that requires the measurement of the allowance for credit losses to be based on management’s best estimate of lifetime expected credit losses (ECL) inherent in the Corporation’s relevant financial assets. Upon adoption of the standard on January 1, 2020, the Corporation recorded a $3.3 billion, or 32 percent, increase to the allowance for credit losses. After adjusting for deferred taxes and other adoption effects, a $2.4 billion decrease was recorded in retained earnings through a cumulative-effect adjustment. Accounting Principles for Credit Losses The following summarizes the Corporation’s accounting policies for certain credit loss activities. Allowance for Credit Losses The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents management’s estimate of the ECL in the Corporation’s loan and lease portfolio, excluding loans and unfunded lending commitments accounted for under the fair value option. The ECL on funded consumer and commercial loans and leases is referred to as the allowance for loan and lease losses and is reported separately as a contra-asset to loans and leases on the Consolidated Balance Sheet. The ECL for unfunded lending commitments, including home equity lines of credit (HELOCs), standby letters of credit (SBLCs) and binding unfunded loan commitments is reported on the Consolidated Balance Sheet in accrued expenses and other liabilities. The provision for credit losses related to the loan and lease portfolio and unfunded lending commitments is reported in the Consolidated Statement of Income. For loans and leases, the ECL is typically estimated using quantitative methods that consider a variety of factors such as historical loss experience, the current credit quality of the portfolio as well as an economic outlook over the life of the loan. The life of the loan for closed-ended products is based on the contractual maturity of the loan adjusted for any expected prepayments. The contractual maturity includes any extension options that are at the sole discretion of the borrower. For open-ended products (e.g., lines of credit), the ECL is determined based on the maximum repayment term associated with future draws from credit lines unless those lines of credit are unconditionally cancellable (e.g., credit cards) in which case the Corporation does not record any allowance. In its loss forecasting framework, the Corporation incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios include variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to, unemployment rates, real estate prices, gross domestic product levels, corporate bond spreads and long-term interest rate forecasts. As any one economic outlook is inherently uncertain, the Corporation leverages multiple scenarios. The scenarios that are chosen each quarter and the amount of weighting given to each scenario depend on a variety of factors including recent economic events, leading economic indicators, views of internal as well as third-party economists and industry trends. The estimate of credit losses includes expected recoveries of amounts previously charged off (i.e., negative allowance). If a loan has been charged off, the expected cash flows on the loan are not limited by the current amortized cost balance. Instead, expected cash flows can be assumed up to the unpaid principal balance immediately prior to the charge-off. The allowance for loan and lease losses for troubled debt restructurings (TDR) is measured based on the present value of projected future lifetime principal and interest cash flows discounted at the loan’s original effective interest rate, or in cases where foreclosure is probable or the loan is collateral dependent, at the loan’s collateral value or its observable market price, if available. The measurement of ECL for the renegotiated consumer credit card TDR portfolio is based on the present value of projected cash flows discounted using the average TDR portfolio contractual interest rate, excluding promotionally priced loans, in effect prior to restructuring. Projected cash flows for TDRs use the same economic outlook as discussed above. For purposes of computing this specific loss component of the allowance, larger impaired loans are evaluated individually and smaller impaired loans are evaluated as a pool. Also included in the allowance for loan and lease losses are qualitative reserves to cover losses that are expected but, in the Corporation's assessment, may not be adequately represented in the quantitative methods or the economic assumptions described above. For example, factors that the Corporation considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and nonaccrual loans, the effect of external factors such as competition, and legal and regulatory requirements, among others. Further, the Corporation considers the inherent uncertainty in quantitative models that are built on historical data. With the exception of the Corporation's credit card portfolio, the Corporation does not include reserves for interest receivable in the measurement of the allowance for credit losses as the Corporation generally classifies consumer loans as nonperforming at 90 days past due and reverses interest income for these loans at that time. For credit card loans, the Corporation reserves for interest and fees as part of the allowance for loan and lease losses. Upon charge-off of a credit card loan, the Corporation reverses the interest and fee income against the income statement line item where it was originally recorded. The Corporation has identified the following three portfolio segments and measures the allowance for credit losses using the following methods. Consumer Real Estate To estimate ECL for consumer loans secured by residential real estate, the Corporation estimates the number of loans that will default over the life of the existing portfolio, after factoring in estimated prepayments, using quantitative modeling methodologies. The attributes that are most significant in estimating the Corporation’s ECL include refreshed loan-to-value (LTV) or, in the case of a subordinated lien, refreshed combined LTV (CLTV), borrower credit score, months since origination and geography, all of which are further broken down by present collection status (whether the loan is current, delinquent, in default, or in bankruptcy). The estimates are based on the Corporation’s historical experience with the loan portfolio, adjusted to reflect the economic outlook. The outlook on the unemployment rate and consumer real estate prices are key factors that impact the frequency and severity of loss estimates. The Corporation does not reserve for credit losses on the unpaid principal balance of loans insured by the Federal Housing Administration (FHA) and long-term standby loans, as these loans are fully insured. The Corporation records a reserve for unfunded lending commitments for the ECL associated with the undrawn portion of the Corporation’s HELOCs, which can only be canceled by the Corporation if certain criteria are met. The ECL associated with these unfunded lending commitments is calculated using the same models and methodologies noted above and incorporate utilization assumptions at time of default. For loans that are more than 180 days past due and collateral-dependent TDRs, the Corporation bases the allowance on the estimated fair value of the underlying collateral as of the reporting date less costs to sell. The fair value of the collateral securing these loans is generally determined using an automated valuation model (AVM) that estimates the value of a property by reference to market data including sales of comparable properties and price trends specific to the Metropolitan Statistical Area in which the property being valued is located. In the event that an AVM value is not available, the Corporation utilizes publicized indices or if these methods provide less reliable valuations, the Corporation uses appraisals or broker price opinions to estimate the fair value of the collateral. While there is inherent imprecision in these valuations, the Corporation believes that they are representative of this portfolio in the aggregate. For loans that are more than 180 days past due and collateral-dependent TDRs, with the exception of the Corporation’s fully insured portfolio, the outstanding balance of loans that is in excess of the estimated property value after adjusting for costs to sell is charged off. If the estimated property value decreases in periods subsequent to the initial charge-off, the Corporation will record an additional charge-off; however, if the value increases in periods subsequent to the charge-off, the Corporation will adjust the allowance to account for the increase but not to a level above the cumulative charge-off amount. Credit Cards and Other Consumer Credit cards are revolving lines of credit without a defined maturity date. The estimated life of a credit card receivable is determined by estimating the amount and timing of expected future payments (e.g., borrowers making full payments, minimum payments or somewhere in between) that it will take for a receivable balance to pay off. The ECL on the future payments incorporates the spending behavior of a borrower through time using key borrower-specific factors and the economic outlook described above. The Corporation applies all expected payments in accordance with the Credit Card Accountability Responsibility and Disclosure Act of 2009 (i.e., paying down the highest interest rate bucket first). Then forecasted future payments are prioritized to pay off the oldest balance until it is brought to zero or an expected charge-off amount. Unemployment rate outlook, borrower credit score, delinquency status and historical payment behavior are all key inputs into the credit card receivable loss forecasting model. Future draws on the credit card lines are excluded from the ECL as they are unconditionally cancellable. The ECL for the consumer vehicle lending portfolio is also determined using quantitative methods supplemented with qualitative analysis. The quantitative model estimates ECL giving consideration to key borrower and loan characteristics such as delinquency status, borrower credit score, LTV ratio, underlying collateral type and collateral value. Commercial The ECL on commercial loans is forecasted using models that estimate credit losses over the loan’s contractual life at an individual loan level. The models use the contractual terms to forecast future principal cash flows while also considering expected prepayments. For open-ended commitments such as revolving lines of credit, changes in funded balance are captured by forecasting a borrower’s draw and payment behavior over the remaining life of the commitment. For loans collateralized with commercial real estate and for which the underlying asset is the primary source of repayment, the loss forecasting models consider key loan and customer attributes such as LTV ratio, net operating income and debt service coverage, and captures variations in behavior according to property type and region. The commercial real estate model also utilizes key economic variables to forecast market indicators such as rent levels and vacancy rates, which impact the ECL estimate. For all other commercial loans and leases, the loss forecasting model determines the probabilities of transition to different credit risk ratings or default at each point over the life of the asset based on the borrower’s current credit risk rating, industry sector, size of the exposure and the geographic market. The severity of loss is determined based on the type of collateral securing the exposure, the size of the exposure, the borrower’s industry sector, any guarantors and the geographic market. Assumptions of expected loss are conditioned to the economic outlook and the model considers key economic variables such as unemployment rate, gross domestic product, credit risk spreads, asset prices and equity market returns. In addition to the allowance for loan and lease losses, the Corporation also estimates ECL related to unfunded lending commitments such as letters of credit, financial guarantees, unfunded bankers acceptances and binding loan commitments, excluding commitments accounted for under the fair value option. Reserves are estimated for the unfunded exposure using the same models and methodologies as the funded exposure and are reported as reserves for unfunded lending commitments. Securities The Corporation evaluates each available-for-sale (AFS) security where the value has declined below amortized cost. If the Corporation intends to sell or believes it is more likely than not that it will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities the Corporation intends to hold, the Corporation evaluates the debt securities for ECL except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality where the Corporation applies a zero credit loss assumption. For the remaining AFS debt securities, the Corporation considers qualitative parameters such as internal and external credit ratings and the value of underlying collateral. If an AFS debt security fails any of the qualitative parameters, a discounted cash flow analysis is used by the Corporation to determine if a portion of the unrealized loss is a result of a credit loss. Any credit losses determined are recognized as an increase to the allowance for credit losses through provision expense recorded in other income. Cash flows expected to be collected are estimated using all relevant information available such as, remaining payment terms, prepayment speeds, the financial condition of the issuer, expected defaults and the value of the underlying collateral. If any of the decline in fair value is related to market factors, that amount is recognized in accumulated other comprehensive income (OCI). In certain instances, the credit loss may exceed the total decline in fair value, in which case, the allowance recorded is limited to the difference between the amortized cost and the fair value of the asset. The Corporation separately evaluates its held-to-maturity (HTM) debt securities for any credit losses, of which substantially all qualify for the zero loss assumption. For the remaining securities, the Corporation performs a discounted cash flow analysis to estimate any credit losses which are then recognized as part of the allowance for credit losses. Other Assets For the Corporation’s financial assets that are measured at amortized cost and are not included in debt securities or loans and leases on the Consolidated Balance Sheet, the Corporation evaluates these assets for ECL using various techniques. For assets that are subject to collateral maintenance provisions, including federal funds sold and securities borrowed or purchased under agreements to resell, where the collateral consists of daily margining of liquid and marketable assets where the margining is expected to be maintained into the foreseeable future, the expected losses are assumed to be zero. For all other assets, the Corporation performs qualitative analyses, including consideration of historical losses and current economic conditions, to estimate any ECL which are then included in a valuation account that is recorded as a contra-asset against the amortized cost basis of the financial asset. Troubled Debt Restructurings The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of the COVID-19 pandemic. In accordance with the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), the Corporation has elected to not apply TDR classification to any COVID-19 related loan modifications that were performed after March 1, 2020 to borrowers who were current as of December 31, 2019. Accordingly, these restructurings are not classified as TDRs. In addition, for loans modified in response to the COVID-19 pandemic that do not meet the above criteria (e.g., current payment status at December 31, 2019), the Corporation is applying the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrowers' past due and nonaccrual status have not been impacted during the deferral period. The Corporation has continued to accrue interest during the deferral period using a constant effective yield method. For most mortgage, HELOC and commercial loan modifications, the contractual interest that accrued during the deferral period is payable at the maturity of the loan. The Corporation includes these amounts with the unpaid principal balance when computing its allowance for credit losses. Amounts that are subsequently deemed uncollectible are written off against the allowance for credit losses. For more information on the Corporation's TDR accounting, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. Paycheck Protection Program The Corporation is participating in the Paycheck Protection Program (PPP), which is a loan program that originated from the CARES Act and was subsequently expanded by the Paycheck Protection Program and Health Care Enhancement Act. The PPP is designed to provide U.S. small businesses with cash-flow assistance through loans fully guaranteed by the Small Business Administration (SBA). If the borrower meets certain criteria and uses the proceeds towards certain eligible expenses, the borrower’s obligation to repay the loan can be forgiven up to the full principal amount of the loan and any accrued interest. Upon borrower forgiveness, the SBA pays the Corporation for the principal and accrued interest owed on the loan. If the full principal of the loan is not forgiven, the loan will operate according to the original loan terms with the 100 percent SBA guaranty remaining. As of September 30, 2020,

Over-the-counter-cleared derivatives include bilateral transactions between the Corporation and a counterparty where the transaction is cleared through a clearinghouse. Exchange-traded derivatives include listed options transacted on an exchange. (2) Consists of derivatives entered into under master netting agreements where the enforceability of these agreements is uncertain under bankruptcy laws in some countries or industries. (3) Amounts are limited to the derivative asset/liability balance and, accordingly, do not include excess collateral received/pledged. Financial instruments collateral includes securities collateral received or pledged and cash securities held and posted at third-party custodians that are not offset on the Consolidated Balance Sheet but shown as a reduction to derive net derivative assets and liabilities. ALM and Risk Management Derivatives The Corporation’s asset and liability management (ALM) and risk management activities include the use of derivatives to mitigate risk to the Corporation including derivatives designated in qualifying hedge accounting relationships and derivatives used in other risk management activities. For more information on ALM and risk management derivatives, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. Derivatives Designated as Accounting Hedges The Corporation uses various types of interest rate and foreign exchange derivative contracts to protect against changes in the fair value of its assets and liabilities due to fluctuations in interest rates and exchange rates (fair value hedges). The Corporation also uses these types of contracts to protect against changes in the cash flows of its assets and liabilities, and other forecasted transactions (cash flow hedges). The Corporation hedges its net investment in consolidated non-U.S. operations determined to have functional currencies other than the U.S. dollar using forward exchange contracts and cross-currency basis swaps, and by issuing foreign currency-denominated debt (net investment hedges). Fair Value Hedges The following table summarizes information related to fair value hedges for the three and nine months ended September 30, 2020 and 2019. Gains and Losses on Derivatives Designated as Fair Value Hedges Three Months Ended September 30, 2020 Three Months Ended September 30, 2019 (Dollars in millions) Derivative Hedged Item Derivative Hedged Item Interest rate risk on long-term debt (1) $ (1,523) $ 1,473 $ 3,328 $ (3,342) Interest rate and foreign currency risk on long-term debt (2) 79 (87) (110) 111 Interest rate risk on available-for-sale securities (3) 139 (139) (33) 30 Total $ (1,305) $ 1,247 $ 3,185 $ (3,201) Nine Months Ended September 30, 2020 Nine Months Ended September 30, 2019 Derivative Hedged Item Derivative Hedged Item Interest rate risk on long-term debt (1) $ 9,286 $ (9,403) $ 9,373 $ (9,392) Interest rate and foreign currency risk on long-term debt (2) 644 (638) (12) 31 Interest rate risk on available-for-sale securities (3) (572) 559 (133) 128 Total $ 9,358 $ (9,482) $ 9,228 $ (9,233) (1) Amounts are recorded in interest expense in the Consolidated Statement of Income. (2) For the three and nine months ended September 30, 2020, the derivative amount includes gains (losses) of $(13) million and $718 million in interest expense, $95 million and $(83) million in market making and similar activities, and $(3) million and $9 million in accumulated OCI. For the same periods in 2019, the derivative amount includes gains (losses) of $(59) million and $108 million in interest expense, $(53) million and $(142) million in market making and similar activities, and $2 million and $22 million in accumulated OCI. Line item totals are in the Consolidated Statement of Income and on the Consolidated Balance Sheet. (3) Amounts are recorded in interest income in the Consolidated Statement of Income. The table below summarizes the carrying value of hedged assets and liabilities that are designated and qualifying in fair value hedging relationships along with the cumulative amount of fair value hedging adjustments included in the carrying value that have been recorded in the current hedging relationships. These fair value hedging adjustments are open basis adjustments that are not subject to amortization as long as the hedging relationship remains designated. Designated Fair Value Hedged Assets (Liabilities) September 30, 2020 December 31, 2019 (Dollars in millions) Carrying Value Cumulative Fair Value Adjustments (1) Carrying Value Cumulative Fair Value Adjustments (1) Long-term debt (2) $ (126,852) $ (12,071) $ (162,389) $ (8,685) Available-for-sale debt securities (2, 3, 4) 102,474 566 1,654 64 (1) For assets, increase (decrease) to carrying value and for liabilities, (increase) decrease to carrying value. (2) At September 30, 2020, the cumulative fair value adjustments remaining on long-term debt and AFS debt securities from discontinued hedging relationships resulted in an increase in the related liability of $1.3 billion and a decrease in the related asset of $6 million compared to a decrease in the related liability of $1.3 billion and an increase in the related asset of $8 million at December 31, 2019, which are being amortized over the remaining contractual life of the de-designated hedged items. (3) These amounts include the amortized cost basis of the prepayable financial assets used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. At September 30, 2020, the amortized cost of the closed portfolios used in these hedging relationships was $40.2 billion, of which $8.4 billion was designated in the hedging relationship. The cumulative basis adjustments associated with these hedging relationships totaled $33 million. (4) Carrying value represents amortized cost. Cash Flow and Net Investment Hedges The following table summarizes certain information related to cash flow hedges and net investment hedges for the three and nine months ended September 30, 2020 and 2019. Of the $408 million after-tax net gain ($542 million pretax) on derivatives in accumulated OCI at September 30, 2020, gains of $191 million after-tax ($252 million pretax) related to open cash flow hedges are expected to be reclassified into earnings in the next 12 months. These net gains reclassified into earnings are expected to primarily increase net interest income related to the respective hedged items. For terminated cash flow hedges, the time period over which the majority of the forecasted transactions are hedged is approximately 3 years, with a maximum length of time for certain forecasted transactions of 16 years. Gains and Losses on Derivatives Designated as Cash Flow and Net Investment Hedges Gains (Losses) Recognized in Gains (Losses) Gains (Losses) Recognized in Gains (Losses) (Dollars in millions, amounts pretax) Three Months Ended September 30, 2020 Nine Months Ended September 30, 2020 Cash flow hedges Interest rate risk on variable-rate assets (1) $ (101) $ 5 $ 810 $ (44) Price risk on forecasted MBS purchases (1) 184 3 184 3 Price risk on certain compensation plans (2) 32 5 23 5 Total $ 115 $ 13 $ 1,017 $ (36) Net investment hedges Foreign exchange risk (3) $ (703) $ — $ 265 $ 1 Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Cash flow hedges Interest rate risk on variable-rate assets (1) $ 125 $ (27) $ 743 $ (78) Net investment hedges Foreign exchange risk (3) $ 786 $ 362 $ 590 $ 363 (1) Amounts reclassified from accumulated OCI are recorded in interest income in the Consolidated Statement of Income. (2) Amounts reclassified from accumulated OCI are recorded in compensation and benefits expense in the Consolidated Statement of Income. (3) Amounts reclassified from accumulated OCI are recorded in other income in the Consolidated Statement of Income. For the three and nine months ended September 30, 2020, amounts excluded from effectiveness testing and recognized in market making and similar activities were gains of $10 million and $115 million. For the same periods in 2019, amounts excluded from effectiveness testing and recognized in market making and similar activities were gains of $32 million and $109 million. Other Risk Management Derivatives Other risk management derivatives are used by the Corporation to reduce certain risk exposures by economically hedging various assets and liabilities. The following table presents gains (losses) on these derivatives for the three and nine months ended September 30, 2020 and 2019. These gains (losses) are largely offset by the income or expense recorded on the hedged item. Gains and Losses on Other Risk Management Derivatives Three Months Ended September 30 Nine Months Ended September 30 (Dollars in millions) 2020 2019 2020 2019 Interest rate risk on mortgage activities (1, 2) $ 32 $ 110 $ 473 $ 361 Credit risk on loans (2) (28) (8) (6) (48) Interest rate and foreign currency risk on ALM activities (3) (2,571) 1,576 (2,060) 2,450 Price risk on certain compensation plans (4) 263 (7) 109 629 (1) Primarily related to hedges of interest rate risk on mortgage servicing rights and interest rate lock commitments to originate mortgage loans that will be held for sale. The net gains on interest rate lock commitments which are not included in the table but are considered derivative instruments, were $41 million and $128 million for the three and nine months ended September 30, 2020 compared to $20 million and $56 million for the same periods in 2019 . (2) Gains (losses) on these derivatives are recorded in other income. (3) Gains (losses) on these derivatives are recorded in market making and similar activities. (4) Gains (losses) on these derivatives are recorded in compensation and benefits expense. Transfers of Financial Assets with Risk Retained through Derivatives The Corporation enters into certain transactions involving the transfer of financial assets that are accounted for as sales where substantially all of the economic exposure to the transferred financial assets is retained through derivatives (e.g., interest rate and/or credit), but the Corporation does not retain control over the assets transferred. At September 30, 2020 and December 31, 2019, the Corporation had transferred $5.1 billion and $5.2 billion of non-U.S. government-guaranteed mortgage-backed securities (MBS) to a third-party trust and retained economic exposure to the transferred assets through derivative contracts. In connection with these transfers, the Corporation received gross cash proceeds of $5.1 billion and $5.2 billion at the transfer dates. At September 30, 2020 and December 31, 2019, the fair value of the transferred securities was $5.2 billion and $5.3 billion. Sales and Trading Revenue The Corporation enters into trading derivatives to facilitate client transactions and to manage risk exposures arising from trading account assets and liabilities. It is the Corporation’s policy to include these derivative instruments in its trading activities, which include derivatives and non-derivative cash instruments. The resulting risk from these derivatives is managed on a portfolio basis as part of the Corporation’s Global Markets business segment. For more information on sales and trading revenue, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. The following table, which includes both derivatives and non-derivative cash instruments, identifies the amounts in the respective income statement line items attributable to the Corporation’s sales and trading revenue in Global Markets , categorized by primary risk, for the three and nine months ended September 30, 2020 and 2019. This table includes debit valuation adjustment (DVA) and funding valuation adjustment (FVA) gains (losses). Global Markets results in Note 17 – Business Segment Information are presented on a fully taxable-equivalent (FTE) basis. The table below is not presented on an FTE basis.

Includes investment and brokerage services revenue of $430 million and $1.5 billion for the three and nine months ended September 30, 2020 compared to $410 million and $1.3 billion for the same periods in 2019. Credit Derivatives The Corporation enters into credit derivatives primarily to facilitate client transactions and to manage credit risk exposures. Credit derivatives are classified as investment and non-investment grade based on the credit quality of the underlying referenced obligation. The Corporation considers ratings of BBB- or higher as investment grade. Non-investment grade includes non-rated credit derivative instruments. The Corporation discloses internal categorizations of investment grade and non-investment grade consistent with how risk is managed for these instruments. For more information on credit derivatives, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. Credit derivative instruments where the Corporation is the seller of credit protection and their expiration at September 30, 2020 and December 31, 2019 are summarized in the following table. Credit Derivative Instruments Less than One to Three to Over Five Total September 30, 2020 (Dollars in millions) Carrying Value Credit default swaps: Investment grade $ — $ 10 $ 79 $ 213 $ 302 Non-investment grade 54 527 1,059 1,698 3,338 Total 54 537 1,138 1,911 3,640 Total return swaps/options: Investment grade 120 — — — 120 Non-investment grade 508 1 — — 509 Total 628 1 — — 629 Total credit derivatives $ 682 $ 538 $ 1,138 $ 1,911 $ 4,269 Credit-related notes: Investment grade $ — $ 2 $ — $ 579 $ 581 Non-investment grade 6 2 4 1,019 1,031 Total credit-related notes $ 6 $ 4 $ 4 $ 1,598 $ 1,612 Maximum Payout/Notional Credit default swaps: Investment grade $ 45,486 $ 78,733 $ 116,365 $ 34,056 $ 274,640 Non-investment grade 19,008 31,252 44,187 17,721 112,168 Total 64,494 109,985 160,552 51,777 386,808 Total return swaps/options: Investment grade 50,952 61 74 — 51,087 Non-investment grade 31,484 656 — 5 32,145 Total 82,436 717 74 5 83,232 Total credit derivatives $ 146,930 $ 110,702 $ 160,626 $ 51,782 $ 470,040 December 31, 2019 Carrying Value Credit default swaps: Investment grade $ — $ 5 $ 60 $ 164 $ 229 Non-investment grade 70 292 561 808 1,731 Total 70 297 621 972 1,960 Total return swaps/options: Investment grade 35 — — — 35 Non-investment grade 344 — — — 344 Total 379 — — — 379 Total credit derivatives $ 449 $ 297 $ 621 $ 972 $ 2,339 Credit-related notes: Investment grade $ — $ 3 $ 1 $ 639 $ 643 Non-investment grade 6 2 1 1,125 1,134 Total credit-related notes $ 6 $ 5 $ 2 $ 1,764 $ 1,777 Maximum Payout/Notional Credit default swaps: Investment grade $ 55,827 $ 67,838 $ 71,320 $ 17,708 $ 212,693 Non-investment grade 19,049 26,521 29,618 12,337 87,525 Total 74,876 94,359 100,938 30,045 300,218 Total return swaps/options: Investment grade 56,488 — 62 76 56,626 Non-investment grade 28,707 657 104 60 29,528 Total 85,195 657 166 136 86,154 Total credit derivatives $ 160,071 $ 95,016 $ 101,104 $ 30,181 $ 386,372 The notional amount represents the maximum amount payable by the Corporation for most credit derivatives. However, the Corporation does not monitor its exposure to credit derivatives based solely on the notional amount because this measure does not take into consideration the probability of occurrence. As such, the notional amount is not a reliable indicator of the Corporation’s exposure to these contracts. Instead, a risk framework is used to define risk tolerances and establish limits so that certain credit risk-related losses occur within acceptable, predefined limits. Credit-related notes in the table above include investments in securities issued by collateralized debt obligation (CDO), collateralized loan obligation and credit-linked note vehicles. These instruments are primarily classified as trading securities. The carrying value of these instruments equals the Corporation’s maximum exposure to loss. The Corporation is not obligated to make any payments to the entities under the terms of the securities owned. Credit-related Contingent Features and Collateral Certain of the Corporation’s derivative contracts contain credit risk-related contingent features, primarily in the form of ISDA master netting agreements and credit support documentation that enhance the creditworthiness of these instruments compared to other obligations of the respective counterparty with whom the Corporation has transacted. These contingent features may be for the benefit of the Corporation as well as its counterparties with respect to changes in the Corporation’s creditworthiness and the mark-to-market exposure under the derivative transactions. At September 30, 2020 and December 31, 2019, the Corporation held cash and securities collateral of $91.7 billion and $84.3 billion and posted cash and securities collateral of $79.9 billion and $69.1 billion in the normal course of business under derivative agreements, excluding cross-product margining agreements where clients are permitted to margin on a net basis for both derivative and secured financing arrangements. In connection with certain over-the-counter derivative contracts and other trading agreements, the Corporation can be required to provide additional collateral or to terminate transactions with certain counterparties in the event of a downgrade of the senior debt ratings of the Corporation or certain subsidiaries. The amount of additional collateral required depends on the contract and is usually a fixed incremental amount and/or the market value of the exposure. For more information on credit-related contingent features and collateral, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. At September 30, 2020, the amount of collateral, calculated based on the terms of the contracts, that the Corporation and certain subsidiaries could be required to post to counterparties but had not yet posted to counterparties was $1.9 billion, including $945 million for Bank of America, National Association. Some counterparties are currently able to unilaterally terminate certain contracts, or the Corporation or certain subsidiaries may be required to take other action such as find a suitable replacement or obtain a guarantee. At September 30, 2020 and December 31, 2019, the liability recorded for these derivative contracts was not significant. The following table presents the amount of additional collateral that would have been contractually required by derivative contracts and other trading agreements at September 30, 2020 if the rating agencies had downgraded their long-term senior debt ratings for the Corporation or certain subsidiaries by one incremental notch and by an additional second incremental notch.

The following table presents the derivative liabilities that would be subject to unilateral termination by counterparties and the amounts of collateral that would have been contractually required at September 30, 2020 if the long-term senior debt ratings for the Corporation or certain subsidiaries had been lower by one incremental notch and by an additional second incremental notch.

(4) The Corporation held debt securities from Fannie Mae and Freddie Mac that each exceeded 10 percent of shareholders’ equity, with an amortized cost of $193.8 billion and $76.9 billion, and a fair value of $201.0 billion and $79.3 billion at September 30, 2020, and an amortized cost of $157.2 billion and $54.1 billion, and a fair value of $160.6 billion and $55.1 billion at December 31, 2019. At September 30, 2020, the accumulated net unrealized gain on AFS debt securities, excluding the amount related to debt securities previously transferred to held to maturity, included in accumulated OCI was $4.8 billion, net of the related income tax expense of $1.6 billion. The Corporation had nonperforming AFS debt securities of $25 million and $9 million at September 30, 2020 and December 31, 2019. Effective January 1, 2020, the Corporation adopted the new accounting standard for credit losses that requires evaluation of AFS and HTM debt securities for any expected losses with recognition of an allowance for credit losses, when applicable. For more information, see Note 1 – Summary of Significant Accounting Principles . At September 30, 2020, the Corporation had $194.8 billion in AFS debt securities, which were primarily U.S. agency and U.S. Treasury securities that have a zero credit loss assumption. For the remaining $38.9 billion in AFS debt securities, the amount of ECL was insignificant. Substantially all of the Corporation's HTM debt securities are U.S. agency and U.S. Treasury securities and have a zero credit loss assumption. At September 30, 2020, the Corporation held equity securities at an aggregate fair value of $809 million and other equity securities, as valued under the measurement alternative, at a carrying value of $261 million, both of which are included in other assets. At September 30, 2020, the Corporation also held money market investments at a fair value of $385 million, which are included in time deposits placed and other short-term investments. In the three and nine months ended September 30, 2020, the Corporation recorded gross realized gains on sales of AFS debt securities of $4 million and $383 million and gross realized losses of $2 million and $4 million, resulting in net gains of $2 million and $379 million, with $1 million and $95 million of income taxes attributable to the realized net gain on sales of these AFS debt securities. Sales of AFS debt securities during the three months ended September 30, 2019 were not significant. In the nine months ended September 30, 2019, the Corporation recorded gross realized gains on sales of AFS debt securities of $228 million and gross realized losses of $112 million, resulting in net gains of $116 million with $28 million of income taxes attributable to the realized net gains on sales of these AFS debt securities. The table below presents the fair value and the associated gross unrealized losses on AFS debt securities and whether these securities have had gross unrealized losses for less than 12 months or for 12 months or longer at September 30, 2020 and December 31, 2019.

(5) Total outstandings includes loans and leases pledged as collateral of $25.9 billion. The Corporation also pledged $168.2 billion of loans with no related outstanding borrowings to secure potential borrowing capacity with the Federal Reserve Bank and Federal Home Loan Bank. The Corporation categorizes consumer real estate loans as core and non-core based on loan and customer characteristics such as origination date, product type, LTV, Fair Isaac Corporation (FICO) score and delinquency status consistent with its current consumer and mortgage servicing strategy. Generally, loans that were originated after January 1, 2010, qualified under government-sponsored enterprise (GSE) underwriting guidelines, or otherwise met the Corporation’s underwriting guidelines in place in 2015 are characterized as core loans. All other loans are generally characterized as non-core loans and represent runoff portfolios. The Corporation has entered into long-term credit protection agreements with Fannie Mae and Freddie Mac on loans totaling $8.8 billion and $7.5 billion at September 30, 2020 and December 31, 2019, providing full credit protection on residential mortgage loans that become severely delinquent. All of these loans are individually insured, and therefore the Corporation does not record an allowance for credit losses related to these loans. Nonperforming Loans and Leases Commercial nonperforming loans increased to $2.2 billion at September 30, 2020 from $1.5 billion at December 31, 2019 with broad-based increases across multiple industries. Consumer nonperforming loans increased to $2.4 billion at September 30, 2020 from $2.1 billion at December 31, 2019 driven by loans with deferrals that expired and have subsequently become nonperforming, as well as the inclusion of $137 million of certain loans that were previously classified as purchased credit-impaired loans and accounted for under a pool basis. The table below presents the Corporation’s nonperforming loans and leases including nonperforming TDRs, and loans accruing past due 90 days or more at September 30, 2020 and December 31, 2019. Nonperforming loans held-for-sale (LHFS) are excluded from nonperforming loans and leases as they are recorded at either fair value or the lower of cost or fair value. For information on the Corporation's interest accrual policies and delinquency status for loan modifications related to the COVID-19 pandemic, see Note 1 – Summary of Significant Accounting Principles . For more information on the criteria for classification as nonperforming, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K.

(2) Residential mortgage loans accruing past due 90 days or more are fully-insured loans. At September 30, 2020 and December 31, 2019 residential mortgage includes $561 million and $740 million of loans on which interest had been curtailed by the FHA, and therefore were no longer accruing interest, although principal was still insured, and $276 million and $348 million of loans on which interest was still accruing. (3) At September 30, 2020, Residential Mortgage and Home Equity include negative allowance on nonperforming loans of $170 million and $106 million. n/a = not applicable Credit Quality Indicators The Corporation monitors credit quality within its Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments based on primary credit quality indicators. For more information on the portfolio segments, see Note 1 – Summary of Significant Accounting Principles . Within the Consumer Real Estate portfolio segment, the primary credit quality indicators are refreshed LTV and refreshed FICO score. Refreshed LTV measures the carrying value of the loan as a percentage of the value of the property securing the loan, refreshed quarterly. Home equity loans are evaluated using CLTV, which measures the carrying value of the Corporation’s loan and available line of credit combined with any outstanding senior liens against the property as a percentage of the value of the property securing the loan, refreshed quarterly. FICO score measures the creditworthiness of the borrower based on the financial obligations of the borrower and the borrower’s credit history. FICO scores are typically refreshed quarterly or more frequently. Certain borrowers (e.g., borrowers that have had debts discharged in a bankruptcy proceeding) may not have their FICO scores updated. FICO scores are also a primary credit quality indicator for the Credit Card and Other Consumer portfolio segment and the business card portfolio within U.S. small business commercial. Within the Commercial portfolio segment, loans are evaluated using the internal classifications of pass rated or reservable criticized as the primary credit quality indicators. The term reservable criticized refers to those commercial loans that are internally classified or listed by the Corporation as Special Mention, Substandard or Doubtful, which are asset quality categories defined by regulatory authorities. These assets have an elevated level of risk and may have a high probability of default or total loss. Pass rated refers to all loans not considered reservable criticized. In addition to these primary credit quality indicators, the Corporation uses other credit quality indicators for certain types of loans. The following tables present certain credit quality indicators for the Corporation's Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments by class of financing receivables and year of origination for term loan balances at September 30, 2020, including revolving loans that converted to term loans without an additional credit decision after origination or through a TDR.

Troubled Debt Restructurings The Corporation began entering into loan modifications with borrowers in response to the COVID-19 pandemic, which have not been classified as TDRs, and therefore are not included in the discussion below. For more information on the criteria for classifying loans as TDRs, see Note 1 – Summary of Significant Accounting Principles . Consumer Real Estate Modifications of consumer real estate loans are classified as TDRs when the borrower is experiencing financial difficulties and a concession has been granted. Concessions may include reductions in interest rates, capitalization of past due amounts, principal and/or interest forbearance, payment extensions, principal and/or interest forgiveness, or combinations thereof. Prior to permanently modifying a loan, the Corporation may enter into trial modifications with certain borrowers under both government and proprietary programs. Trial modifications generally represent a three- to four-month period during which the borrower makes monthly payments under the anticipated modified payment terms. Upon successful completion of the trial period, the Corporation and the borrower enter into a permanent modification. Binding trial modifications are classified as TDRs when the trial offer is made and continue to be classified as TDRs regardless of whether the borrower enters into a permanent modification. Consumer real estate loans of $385 million that have been discharged in Chapter 7 bankruptcy with no change in repayment terms and not reaffirmed by the borrower were included in TDRs at September 30, 2020, of which $101 million were classified as nonperforming and $71 million were loans fully insured. Consumer real estate TDRs are measured primarily based on the net present value of the estimated cash flows discounted at the loan’s original effective interest rate. If the carrying value of a TDR exceeds this amount, a specific allowance is recorded as a component of the allowance for loan and lease losses. Alternatively, consumer real estate TDRs that are considered to be dependent solely on the collateral for repayment (e.g., due to the lack of income verification) are measured based on the estimated fair value of the collateral, and a charge-off is recorded if the carrying value exceeds the fair value of the collateral. Consumer real estate loans that reach 180 days past due prior to modification are charged off to their net realizable value, less costs to sell, before they are modified as TDRs in accordance with established policy. Subsequent declines in the fair value of the collateral after a loan has reached 180 days past due are recorded as charge-offs. Fully-insured loans are protected against principal loss, and therefore, the Corporation does not record an allowance for loan and lease losses on the outstanding principal balance, even after they have been modified in a TDR. At September 30, 2020 and December 31, 2019, remaining commitments to lend additional funds to debtors whose terms have been modified in a consumer real estate TDR were not significant. Consumer real estate foreclosed properties totaled $135 million and $229 million at September 30, 2020 and December 31, 2019. The carrying value of consumer real estate loans, including fully-insured loans, for which formal foreclosure proceedings were in process at September 30, 2020 was $1.3 billion. Although the Corporation has paused formal loan foreclosure proceedings and foreclosure sales for occupied properties, during the nine months ended September 30, 2020, the Corporation reclassified $169 million of consumer real estate loans completed or which were in process prior to the pause in foreclosures, to foreclosed properties or, for properties acquired upon foreclosure of certain government-guaranteed loans (principally FHA-insured loans), to other assets. The reclassifications represent non-cash investing activities and, accordingly, are not reflected in the Consolidated Statement of Cash Flows. The table below presents the September 30, 2020 and 2019 unpaid principal balance, carrying value, and average pre- and post-modification interest rates of consumer real estate loans that were modified in TDRs during the three and nine months ended September 30, 2020 and 2019. The following Consumer Real Estate portfolio segment tables include loans that were initially classified as TDRs during the period and also loans that had previously been classified as TDRs and were modified again during the period.

(2) Includes loans discharged in Chapter 7 bankruptcy with no change in repayment terms that are classified as TDRs. (3) Includes trial modification offers to which the customer did not respond. Credit Card and Other Consumer The Corporation seeks to assist customers that are experiencing financial difficulty by modifying loans while ensuring compliance with federal and local laws and guidelines. Credit card and other consumer loan modifications generally involve reducing the interest rate on the account, placing the customer on a fixed payment plan not exceeding 60 months and canceling the customer’s available line of credit, all of which are considered TDRs. The Corporation makes loan modifications directly with borrowers for debt held only by the Corporation (internal programs). Additionally, the Corporation makes loan modifications for borrowers working with third-party renegotiation agencies that provide solutions to customers’ entire unsecured debt structures (external programs). The Corporation classifies other secured consumer loans that have been discharged in Chapter 7 bankruptcy as TDRs which are written down to collateral value and placed on nonaccrual status no later than the time of discharge. The table below provides information on the Corporation’s Credit Card and Other Consumer TDR portfolio including the September 30, 2020 and 2019 unpaid principal balance, carrying value, and average pre- and post-modification interest rates of loans that were modified in TDRs during the three and nine months ended September 30, 2020 and 2019.

For more information on the Corporation's loan modification programs offered in response to the COVID-19 pandemic, which are not TDRs, see Note 1 – Summary of Significant Accounting Principles. Commercial Loans Modifications of loans to commercial borrowers that are experiencing financial difficulty are designed to reduce the Corporation’s loss exposure while providing the borrower with an opportunity to work through financial difficulties, often to avoid foreclosure or bankruptcy. Each modification is unique and reflects the individual circumstances of the borrower. Modifications that result in a TDR may include extensions of maturity at a concessionary (below market) rate of interest, payment forbearances or other actions designed to benefit the borrower while mitigating the Corporation’s risk exposure. Reductions in interest rates are rare. Instead, the interest rates are typically increased, although the increased rate may not represent a market rate of interest. Infrequently, concessions may also include principal forgiveness in connection with foreclosure, short sale or other settlement agreements leading to termination or sale of the loan. At the time of restructuring, the loans are remeasured to reflect the impact, if any, on projected cash flows resulting from the modified terms. If a portion of the loan is deemed to be uncollectible, a charge-off may be recorded at the time of restructuring. Alternatively, a charge-off may have already been recorded in a previous period such that no charge-off is required at the time of modification. For more information on modifications for the U.S. small business commercial portfolio, see Credit Card and Other Consumer in this Note. At September 30, 2020 and December 31, 2019, remaining commitments to lend additional funds to debtors whose terms have been modified in a commercial loan TDR were $471 million and $445 million. The balance of commercial TDRs in payment default was $391 million at September 30, 2020 and $207 million at December 31, 2019. Loans Held-for-sale The Corporation had LHFS of $4.4 billion and $9.2 billion at September 30, 2020 and December 31, 2019. Cash and non-cash proceeds from sales and paydowns of loans originally classified as LHFS were $16.1 billion and $19.6 billion for the nine months ended September 30, 2020 and 2019. Cash used for originations and purchases of LHFS totaled approximately $11.1 billion and $18.7 billion for the nine months ended September 30, 2020 and 2019. Accrued Interest Receivable Accrued interest receivable for loans and leases and loans held-for-sale at September 30, 2020 and December 31, 2019 was $2.5 billion and $2.6 billion and is reported in customer and other receivables on the Consolidated Balance Sheet. Outstanding credit card loan balances include unpaid principal, interest and fees. Credit card loans are not classified as nonperforming but are charged off no later than the end of the month in which the account becomes 180 days past due, within 60 days after receipt of notification of death or bankruptcy, or upon confirmation of fraud .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Securitizations and Other Variable Interest Entities	Securitizations and Other Variable Interest Entities The Corporation utilizes VIEs in the ordinary course of business to support its own and its customers’ financing and investing needs. The tables in this Note present the assets, liabilities and maximum loss exposure of consolidated and unconsolidated VIEs at September 30, 2020 and December 31, 2019 in situations where the Corporation has continuing involvement with transferred assets or if the Corporation otherwise has a variable interest in the VIE. For more information on the Corporation's use of VIEs and related maximum loss exposure, see Note 1 – Summary of Significant Accounting Principles and Note 7 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K . The Corporation invests in ABS issued by third-party VIEs with which it has no other form of involvement and enters into certain commercial lending arrangements that may also incorporate the use of VIEs, for example to hold collateral. These securities and loans are included in Note 4 – Securities or Note 5 – Outstanding Loans and Leases and Allowance for Credit Losses. The Corporation did not provide financial support to consolidated or unconsolidated VIEs during the nine months ended September 30, 2020 or the year ended December 31, 2019 that it was not previously contractually required to provide, nor does it intend to do so. The Corporation had liquidity commitments, including written put options and collateral value guarantees, with certain unconsolidated VIEs of $918 million and $1.1 billion at September 30, 2020 and December 31, 2019. First-lien Mortgage Securitizations As part of its mortgage banking activities, the Corporation securitizes a portion of the first-lien residential mortgage loans it originates or purchases from third parties. Except as described in Note 10 – Commitments and Contingencies , the Corporation does not provide guarantees or recourse to the securitization trusts other than standard representations and warranties. The table below summarizes select information related to first-lien mortgage securitizations for the three and nine months ended September 30, 2020 and 2019. First-lien Mortgage Securitizations Residential Mortgage - Agency Commercial Mortgage Three Months Ended September 30 Nine Months Ended September 30 Three Months Ended September 30 Nine Months Ended September 30 (Dollars in millions) 2020 2019 2020 2019 2020 2019 2020 2019 Proceeds from loan sales (1) $ 1,698 $ 2,718 $ 14,625 $ 6,020 $ 945 $ 1,360 $ 3,237 $ 4,541 Gains (losses) on securitizations (2) 3 8 724 23 17 28 57 73 Repurchases from securitization trusts (3) 68 209 363 695 — — — — (1) The Corporation transfers residential mortgage loans to securitizations sponsored primarily by the GSEs or Government National Mortgage Association (GNMA) in the normal course of business and primarily receives residential mortgage-backed securities in exchange. Substantially all of these securities are classified as Level 2 within the fair value hierarchy and are typically sold shortly after receipt. (2) A majority of the first-lien residential mortgage loans securitized are initially classified as LHFS and accounted for under the fair value option. Gains recognized on these LHFS prior to securitization, which totaled $44 million and $105 million, net of hedges, during the three and nine months ended September 30, 2020 compared to $19 million and $38 million for the same periods in 2019, are not included in the table above. (3) The Corporation may have the option to repurchase delinquent loans out of securitization trusts, which reduces the amount of servicing advances it is required to make. The Corporation may also repurchase loans from securitization trusts to perform modifications. Repurchased loans include FHA-insured mortgages collateralizing GNMA securities. The Corporation recognizes consumer mortgage servicing rights (MSRs) from the sale or securitization of consumer real estate loans. The unpaid principal balance of loans serviced for investors, including residential mortgage and home equity loans, totaled $172.5 billion and $201.3 billion at September 30, 2020 and 2019. Servicing fee and ancillary fee income on serviced loans was $101 million and $353 million during the three and nine months ended September 30, 2020 compared to $144 million and $436 million for the same periods in 2019. Servicing advances on serviced loans, including loans serviced for others and loans held for investment, were $2.1 billion and $2.4 billion at September 30, 2020 and December 31, 2019. For more information on MSRs, see Note 14 – Fair Value Measurements . During the three and nine months ended September 30, 2019, the Corporation deconsolidated agency residential mortgage securitization trusts with total assets of $65 million and $1.2 billion. During the nine months ended September 30, 2020, the Corporation completed the sale of $9.3 billion of consumer real estate loans through GNMA loan securitizations. As part of the securitizations, the Corporation retained $8.4 billion of MBS, which are classified as debt securities carried at fair value on the Consolidated Balance Sheet.

(2) Principal balance outstanding includes loans where the Corporation was the transferor to securitization VIEs with which it has continuing involvement, which may include servicing the loans. Other Asset-backed Securitizations The following table summarizes select information related to home equity, credit card and other asset-backed VIEs in which the Corporation held a variable interest at September 30, 2020 and December 31, 2019.

For both consolidated and unconsolidated home equity loan VIEs, the maximum loss exposure excludes the reserve for representations and warranties obligations and corporate guarantees. For more information, see Note 10 – Commitments and Contingencies . (2) At September 30, 2020 and December 31, 2019, loans and leases in the consolidated credit card trust included $9.0 billion and $10.5 billion of seller’s interest. (3) The retained senior securities were valued using quoted market prices or observable market inputs (Level 2 of the fair value hierarchy). Home Equity Loans The Corporation retains interests, primarily senior securities, in home equity securitization trusts to which it transferred home equity loans. In addition, the Corporation may be obligated to provide subordinate funding to the trusts during a rapid amortization event. This obligation is included in the maximum loss exposure in the table above. The charges that will ultimately be recorded as a result of the rapid amortization events depend on the undrawn portion of the HELOCs, performance of the loans, the amount of subsequent draws and the timing of related cash flows. Credit Card Securitizations The Corporation securitizes originated and purchased credit card loans. The Corporation’s continuing involvement with the securitization trust includes servicing the receivables, retaining an undivided interest (seller’s interest) in the receivables, and holding certain retained interests including subordinate interests in accrued interest and fees on the securitized receivables and cash reserve accounts. During the nine months ended September 30, 2019, there were $1.3 billion of new senior debt securities issued to third-party investors from the credit card securitization trust. There were no new senior debt securities issued to third-party investors from the credit card securitization trust during the nine months ended September 30, 2020. At September 30, 2020 and December 31, 2019, the Corporation held subordinate securities issued by the credit card securitization trust with a notional principal amount of $6.9 billion and $7.4 billion. These securities serve as a form of credit enhancement to the senior debt securities and have a stated interest rate of zero percent. There were $202 million of these subordinate securities issued by the credit card securitization trust during the nine months ended September 30, 2019. There were no subordinate securities issued by the credit card securitization trust during the nine months ended September 30, 2020. Resecuritization Trusts The Corporation transfers securities, typically MBS, into resecuritization VIEs generally at the request of customers seeking securities with specific characteristics. Generally, there are no significant ongoing activities performed in a resecuritization trust, and no single investor has the unilateral ability to liquidate the trust. The Corporation resecuritized $8.3 billion and $26.4 billion of securities during the three and nine months ended September 30, 2020 compared to $5.2 billion and $13.7 billion for the same periods in 2019. Securities transferred into resecuritization VIEs were measured at fair value with changes in fair value recorded in market making and similar activities prior to the resecuritization and, accordingly, no gain or loss on sale was recorded. Securities received from the resecuritization VIEs were recognized at their fair value of $598 million and $5.5 billion during the three and nine months ended September 30, 2020 compared to $750 million and $3.5 billion for the same periods in 2019, of which substantially all of the securities in the prior-year period were classified as trading account assets. All of the securities received as resecuritization proceeds during the three months ended September 30, 2020 were classified as trading account assets. Of the securities received as resecuritizations proceeds during the nine months ended September 30, 2020, $1.8 billion, $2.1 billion and $1.7 billion were classified as trading account assets, debt securities carried at fair value and HTM securities, respectively. Substantially all of the trading account securities and debt securities carried at fair value were categorized as Level 2 within the fair value hierarchy. Municipal Bond Trusts The Corporation administers municipal bond trusts that hold highly-rated, long-term, fixed-rate municipal bonds. The trusts obtain financing by issuing floating-rate trust certificates that reprice on a weekly or other short-term basis to third-party investors. The Corporation’s liquidity commitments to unconsolidated municipal bond trusts, including those for which the Corporation was transferor, totaled $3.3 billion and $3.7 billion at September 30, 2020 and December 31, 2019. The weighted-average remaining life of bonds held in the trusts at September 30, 2020 was 6.9 years. There were no significant write-downs or downgrades of assets or issuers during the nine months ended September 30, 2020 and 2019. Other Variable Interest Entities The table below summarizes select information related to other VIEs in which the Corporation held a variable interest at September 30, 2020 and December 31, 2019.

The Corporation’s maximum loss exposure to consolidated and unconsolidated customer VIEs totaled $2.4 billion and $2.2 billion at September 30, 2020 and December 31, 2019, including the notional amount of derivatives to which the Corporation is a counterparty, net of losses previously recorded, and the Corporation’s investment, if any, in securities issued by the VIEs. Collateralized Debt Obligation VIEs The Corporation receives fees for structuring CDO VIEs, which hold diversified pools of fixed-income securities, typically corporate debt or ABS, which the CDO VIEs fund by issuing multiple tranches of debt and equity securities. CDOs are generally managed by third-party portfolio managers. The Corporation typically transfers assets to these CDOs, holds securities issued by the CDOs and may be a derivative counterparty to the CDOs. The Corporation’s maximum loss exposure to consolidated and unconsolidated CDOs totaled $252 million and $304 million at September 30, 2020 and December 31, 2019. Investment VIEs The Corporation sponsors, invests in or provides financing, which may be in connection with the sale of assets, to a variety of investment VIEs that hold loans, real estate, debt securities or other financial instruments and are designed to provide the desired investment profile to investors or the Corporation. At September 30, 2020 and December 31, 2019, the Corporation’s consolidated investment VIEs had total assets of $552 million and $104 million. The Corporation also held investments in unconsolidated VIEs with total assets of $37.3 billion and $32.4 billion at September 30, 2020 and December 31, 2019. The Corporation’s maximum loss exposure associated with both consolidated and unconsolidated investment VIEs totaled $5.9 billion and $6.4 billion at September 30, 2020 and December 31, 2019 comprised primarily of on-balance sheet assets less non-recourse liabilities. Leveraged Lease Trusts The Corporation’s net investment in consolidated leveraged lease trusts totaled $1.7 billion at both September 30, 2020 and December 31, 2019. The trusts hold long-lived equipment such as rail cars, power generation and distribution equipment, and commercial aircraft. The Corporation structures the trusts and holds a significant residual interest. The net investment represents the Corporation’s maximum loss exposure to the trusts in the unlikely event that the leveraged lease investments become worthless. Debt issued by the leveraged lease trusts is non-recourse to the Corporation. Tax Credit VIEs The Corporation holds investments in unconsolidated limited partnerships and similar entities that construct, own and operate affordable housing, wind and solar projects. An unrelated third party is typically the general partner or managing member and has control over the significant activities of the VIE. The Corporation earns a return primarily through the receipt of tax credits allocated to the projects. The maximum loss exposure included in the Other VIEs table was $20.0 billion and $18.9 billion at September 30, 2020 and December 31, 2019. The Corporation’s risk of loss is generally mitigated by policies requiring that the project qualify for the expected tax credits prior to making its investment. The Corporation’s investments in affordable housing partnerships, which are reported in other assets on the Consolidated Balance Sheet, totaled $10.6 billion and $10.0 billion, including unfunded commitments to provide capital contributions of $4.8 billion and $4.3 billion at September 30, 2020 and December 31, 2019. The unfunded commitments are expected to be paid over the next five years. The Corporation

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, the Corporation enters into a number of off-balance sheet commitments. These commitments expose the Corporation to varying degrees of credit and market risk and are subject to the same credit and market risk limitation reviews as those instruments recorded on the Consolidated Balance Sheet. For more information on commitments and contingencies, see Note 13 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. Credit Extension Commitments The Corporation enters into commitments to extend credit such as loan commitments, SBLCs and commercial letters of credit to meet the financing needs of its customers. The following table includes the notional amount of unfunded legally binding lending commitments net of amounts distributed (i.e., syndicated or participated) to other financial institutions. The distributed amounts were $10.3 billion and $10.6 billion at September 30, 2020 and December 31, 2019. At September 30, 2020, the carrying value of these commitments, excluding commitments accounted for under the fair value option, was $1.9 billion, including deferred revenue of $17 million and a reserve for unfunded lending commitments of $1.9 billion. At December 31, 2019, the comparable amounts were $829 million, $16 million and $813 million, respectively. The carrying value of these commitments is classified in accrued expenses and other liabilities on the Consolidated Balance Sheet. Legally binding commitments to extend credit generally have specified rates and maturities. Certain of these commitments have adverse change clauses that help to protect the Corporation against deterioration in the borrower’s ability to pay. The table below includes the notional amount of commitments of $3.3 billion and $4.4 billion at September 30, 2020 and December 31, 2019 that are accounted for under the fair value option. However, the table excludes cumulative net fair value of $122 million and $90 million at September 30, 2020 and December 31, 2019 on these commitments, which is classified in accrued expenses and other liabilities. For more information regarding the Corporation’s loan commitments accounted for under the fair value option, see Note 15 – Fair Value Option.

(2) The notional amounts of SBLCs and financial guarantees classified as investment grade and non-investment grade based on the credit quality of the underlying reference name within the instrument were $25.4 billion and $10.5 billion at September 30, 2020, and $27.9 billion and $8.6 billion at December 31, 2019. Amounts in the table include consumer SBLCs of $521 million and $413 million at September 30, 2020 and December 31, 2019. (3) At September 30, 2020 and December 31, 2019, included are letters of credit of $1.7 billion and $1.4 billion related to certain liquidity commitments of VIEs. For more information, see Note 6 – Securitizations and Other Variable Interest Entities . (4) Includes business card unused lines of credit. Other Commitments At September 30, 2020 and December 31, 2019, the Corporation had commitments to purchase loans (e.g., residential mortgage and commercial real estate) of $169 million and $86 million, which upon settlement will be included in trading account assets, loans or LHFS, and commitments to purchase commercial loans of $365 million and $1.1 billion, which upon settlement will be included in trading account assets. At September 30, 2020 and December 31, 2019, the Corporation had commitments to purchase commodities, primarily liquefied natural gas, of $539 million and $830 million, which upon settlement will be included in trading account assets. At September 30, 2020 and December 31, 2019, the Corporation had commitments to enter into resale and forward-dated resale and securities borrowing agreements of $127.7 billion and $97.2 billion, and commitments to enter into forward-dated repurchase and securities lending agreements of $68.7 billion and $24.9 billion. These commitments generally expire within the next 12 months. At September 30, 2020 and December 31, 2019, the Corporation had a commitment to originate or purchase up to $3.8 billion and $3.3 billion on a rolling 12-month basis, of auto loans and leases from a strategic partner. This commitment extends through November 2022 and can be terminated with 12 months prior notice. Other Guarantees Bank-owned Life Insurance Book Value Protection The Corporation sells products that offer book value protection to insurance carriers who offer group life insurance policies to corporations, primarily banks. At September 30, 2020 and December 31, 2019, the notional amount of these guarantees totaled $7.1 billion and $7.3 billion. At both September 30, 2020 and December 31, 2019, the Corporation’s maximum exposure related to these guarantees totaled $1.1 billion, with estimated maturity dates between 2033 and 2039. Merchant Services Prior to July 1, 2020, a significant portion of the Corporation's merchant processing activity was performed by a joint venture in which it held a 49 percent ownership interest. On July 29, 2019, the Corporation gave notice to the joint venture partner of the termination of the joint venture upon the conclusion of its current term on June 30, 2020. Effective July 1, 2020, the Corporation received its share of the joint venture's merchant contracts and began performing merchant processing services for these merchants. While merchants bear responsibility for any credit or debit card charges properly reversed by the cardholder, the Corporation, in its role as merchant acquirer, may be held liable for any reversed charges that cannot be collected from the merchants due to, among other things, merchant fraud or insolvency. The Corporation, as a card network member bank, also sponsors other merchant acquirers, principally its former joint venture partner with respect to merchants distributed to that partner upon the termination of the joint venture. If reversed charges applicable to these merchants cannot be collected from either the merchants or merchant acquirers, the Corporation may be held liable for these reversed charges. The Corporation’s risk in this area primarily relates to circumstances where a cardholder has purchased goods or services for future delivery. The Corporation mitigates this risk by requiring cash deposits, guarantees, letters of credit or other types of collateral from certain merchants. The total amount of transactions processed for the preceding six-month period, which was $311.7 billion, is an estimate of the Corporation’s maximum potential exposure as of September 30, 2020. However, for the reasons described above, the Corporation does not believe the maximum potential exposure is representative of the actual potential loss exposure. At September 30, 2020 and 2019, the Corporation’s reserves for contingent losses and the losses incurred related to the merchant processing activity were not significant. The Corporation will continue to monitor its exposure in this area due to the potential economic impacts of COVID-19. Representations and Warranties Obligations and Corporate Guarantees For more information on representations and warranties obligations and corporate guarantees, see Note 13 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. The reserve for representations and warranties obligations and corporate guarantees was $1.4 billion and $1.8 billion at September 30, 2020 and December 31, 2019 and is included in accrued expenses and other liabilities on the Consolidated Balance Sheet and the related provision is included in other income in the Consolidated Statement of Income. The representations and warranties reserve represents the Corporation’s best estimate of probable incurred losses, is based on our experience in previous negotiations, and is subject to judgment, a variety of assumptions, and known or unknown uncertainties. Future representations and warranties losses may occur in excess of the amounts recorded for these exposures; however, the Corporation does not expect such amounts to be material to the Corporation's financial condition and liquidity. See Litigation and Regulatory Matters below for the Corporation's combined range of possible loss in excess of the reserve for representations and warranties and the accrued liability for litigation. Fixed Income Clearing Corporation Sponsored Member Repo Program The Corporation acts as a sponsoring member in a repo program whereby the Corporation clears certain eligible resale and repurchase agreements through the Government Securities Division of the Fixed Income Clearing Corporation on behalf of clients that are sponsored members in accordance with the Fixed Income Clearing Corporation’s rules. As part of this program, the Corporation guarantees the payment and performance of its sponsored members to the Fixed Income Clearing Corporation. The Corporation’s guarantee obligation is secured by a security interest in cash or high-quality securities collateral placed by clients with the clearinghouse and therefore, the potential for the Corporation to incur significant losses under this arrangement is remote. The Corporation’s maximum potential exposure, without taking into consideration the related collateral, was $8.0 billion and $9.3 billion at September 30, 2020 and December 31, 2019. Other Guarantees The Corporation has entered into additional guarantee agreements and commitments, including sold risk participation swaps, liquidity facilities, lease-end obligation agreements, partial credit guarantees on certain leases, real estate joint venture guarantees, divested business commitments and sold put options that require gross settlement. The maximum potential future payments under these agreements are approximately $9.0 billion and $8.7 billion at September 30, 2020 and December 31, 2019. The estimated maturity dates of these obligations extend up to 2049. The Corporation has made no material payments under these guarantees. For more information on maximum potential future payments under VIE-related liquidity commitments, see Note 6 – Securitizations and Other Variable Interest Entities . In the normal course of business, the Corporation periodically guarantees the obligations of its affiliates in a variety of transactions including ISDA-related transactions and non-ISDA related transactions such as commodities trading, repurchase agreements, prime brokerage agreements and other transactions. Guarantees of Certain Long-term Debt The Corporation, as the parent company, fully and unconditionally guarantees the securities issued by BofA Finance LLC, a 100 percent owned finance subsidiary of the Corporation, and effectively provides for the full and unconditional guarantee of trust securities issued by certain statutory trust companies that are 100 percent owned finance subsidiaries of the Corporation. Litigation and Regulatory Matters The following disclosure supplements the disclosure in Note 13 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K (the prior commitments and contingencies disclosure). In the ordinary course of business, the Corporation and its subsidiaries are routinely defendants in or parties to many pending and threatened legal, regulatory and governmental actions and proceedings. In view of the inherent difficulty of predicting the outcome of such matters, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Corporation generally cannot predict the eventual outcome of the pending matters, the timing of the ultimate resolution of these matters, or any eventual loss, fines or penalties related to each pending matter. In accordance with applicable accounting guidance, the Corporation establishes an accrued liability when those matters present loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. As a matter develops, the Corporation, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is probable and estimable. Once the loss contingency is deemed to be both probable and estimable, the Corporation will establish an accrued liability and record a corresponding amount of litigation-related expense. The Corporation continues to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Excluding expenses of internal and external legal service providers, litigation-related expense of $636 million and $717 million was recognized for the three and nine months ended September 30, 2020 compared to $352 million and $539 million for the same periods in 2019. For a limited number of the matters disclosed in the prior commitments and contingencies disclosure, for which a loss, whether in excess of a related accrued liability or where there is no accrued liability, is reasonably possible in future periods, the Corporation is able to estimate a range of possible loss. In determining whether it is possible to estimate a range of possible loss, the Corporation reviews and evaluates these matters on an ongoing basis, in conjunction with any outside counsel handling the matter, in light of potentially relevant factual and legal developments. With respect to such matters, in cases in which the Corporation possesses sufficient appropriate information to estimate a range of possible loss, that estimate is aggregated and disclosed below. There may be other disclosed matters for which a loss is probable or reasonably possible but such an estimate of the range of possible loss may not be possible. For those disclosed matters where an estimate of the range of possible loss is possible, as well as for representations and warranties exposures, management currently estimates the aggregate range of reasonably possible loss for these exposures is $0 to $1.3 billion in excess of the accrued liability, if any. The estimated range of possible loss, as well as the Corporation's accrued liability, is based upon currently available information and is subject to significant judgment, a variety of assumptions and known and unknown uncertainties. The matters underlying the estimated range of possible loss and liability accrual are unpredictable and will change from time to time, and actual losses may vary significantly from the current estimate or accrual. Therefore, this estimated range of possible loss represents what the Corporation believes to be an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Corporation’s maximum loss exposure. Information is provided in the prior commitments and contingencies disclosure regarding the nature of the litigation and, where specified, associated claimed damages. Based on current knowledge, and taking into account accrued liabilities, management does not believe that loss contingencies arising from pending matters in the prior commitments and contingencies disclosure will have a material adverse effect on the consolidated financial condition or liquidity of the Corporation. However, in light of the significant judgment, variety of assumptions and uncertainties involved in these matters, some of which are beyond the Corporation’s control, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to the Corporation’s businesses or results of operations for any particular reporting period, or cause significant reputational harm.

In June 2020, the Board of Governors of the Federal Reserve System (Federal Reserve) announced that due to economic uncertainty resulting from COVID-19, all large banks would be required to suspend share repurchase programs in the third quarter of 2020, except for repurchases to offset shares awarded under equity-based compensation plans, and to limit dividends to existing rates that do not exceed the average of the last four quarters’ net income. The Federal Reserve’s directives regarding share repurchases aligned with the Corporation's decision to voluntarily suspend repurchases during the first half of 2020. The suspension of the Corporation's repurchases did not include repurchases to offset shares awarded under its equity-based compensation plans. During the three and nine months ended September 30, 2020, the Corporation repurchased and retired 4 million and 216 million shares of common stock, which reduced shareholders’ equity by $114 million and $6.8 billion. During the nine months ended September 30, 2020, in connection with employee stock plans, the Corporation issued 66 million shares of its common stock and, to satisfy tax withholding obligations, repurchased 26 million shares of its common stock. At September 30, 2020, the Corporation had reserved 513 million unissued shares of common stock for future issuances under employee stock plans, convertible notes and preferred stock. On October 21, 2020 the Board declared a quarterly common stock dividend at the current rate of $0.18 per share. Preferred Stock During the three months ended March 31, 2020, June 30, 2020 and September 30, 2020, the Corporation declared $469 million, $249 million and $441 million of cash dividends on preferred stock, or a total of $1.2 billion for the nine months ended September 30, 2020. On October 29, 2020, the Corporation issued 44,000 shares of 4.375% Non-Cumulative Preferred Stock, Series NN for $1.1 billion, with quarterly dividends commencing in February 2021. The Series NN preferred stock has a liquidation preference of $25,000 per share and is subject to certain restrictions in the event the Corporation fails to declare and pay full dividends. For more information on the Corporation's preferred stock, including liquidation preference, dividend requirements and redemption period, see Note 14 – Shareholders’ Equity to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value MeasurementsUnder applicable accounting standards, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Corporation determines the fair values of its financial instruments under applicable accounting standards and conducts a review of its fair value hierarchy classifications on a quarterly basis. Transfers into or out of fair value hierarchy classifications are made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities become unobservable or observable in the current marketplace. During the nine months ended September 30, 2020, there were no changes to valuation approaches or techniques that had, or are expected to have, a material impact on the Corporation’s consolidated financial position or results of operations. For more information regarding the fair value hierarchy, how the Corporation measures fair value and valuation techniques, see Note 1 – Summary of Significant Accounting Principles and Note 21 – Fair Value Measurements to the Consolidated Financial Statements of the Corporation’s 2019 Annual Report on Form 10-K. The Corporation accounts for certain financial instruments under the fair value option. For more information, see Note 15 – Fair Value Option . Recurring Fair Value Assets and liabilities carried at fair value on a recurring basis at September 30, 2020 and December 31, 2019, including financial instruments that the Corporation accounts for under the fair value option, are summarized in the following tables.

The following tables present a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three and nine months ended September 30, 2020 and 2019, including net realized and unrealized gains (losses) included in earnings and accumulated OCI. Transfers into Level 3 occur primarily due to decreased price observability, and transfers out of Level 3 occur primarily due to increased price observability. Transfers occur on a regular basis for long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition, and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing, and the Corporation’s proportionate share of income or loss is included in other income.
Basis of Presentation	The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could materially differ from those estimates and assumptions.
Accounting Standards	New Accounting Standards Reference Rate Reform In March 2020, the FASB issued a new accounting standard related to contracts or hedging relationships that reference LIBOR or other reference rates that are expected to be discontinued due to reference rate reform. The new standard provides for optional expedients and other guidance regarding the accounting related to modifications of contracts, hedging relationships and other transactions affected by reference rate reform. The Corporation has elected to retrospectively adopt the new standard as of January 1, 2020 which resulted in no immediate impact. While reference rate reform is not expected to have a material accounting impact on the Corporation’s consolidated financial position or results of operations, the standard will ease the administrative burden in accounting for the future effects of reference rate reform. Accounting for Financial Instruments -- Credit Losses On January 1, 2020, the Corporation adopted the new accounting standard that requires the measurement of the allowance for credit losses to be based on management’s best estimate of lifetime expected credit losses (ECL) inherent in the Corporation’s relevant financial assets. Upon adoption of the standard on January 1, 2020, the Corporation recorded a $3.3 billion, or 32 percent, increase to the allowance for credit losses. After adjusting for deferred taxes and other adoption effects, a $2.4 billion decrease was recorded in retained earnings through a cumulative-effect adjustment. Accounting Principles for Credit Losses The following summarizes the Corporation’s accounting policies for certain credit loss activities. Allowance for Credit Losses The allowance for credit losses includes both the allowance for loan and lease losses and the reserve for unfunded lending commitments and represents management’s estimate of the ECL in the Corporation’s loan and lease portfolio, excluding loans and unfunded lending commitments accounted for under the fair value option. The ECL on funded consumer and commercial loans and leases is referred to as the allowance for loan and lease losses and is reported separately as a contra-asset to loans and leases on the Consolidated Balance Sheet. The ECL for unfunded lending commitments, including home equity lines of credit (HELOCs), standby letters of credit (SBLCs) and binding unfunded loan commitments is reported on the Consolidated Balance Sheet in accrued expenses and other liabilities. The provision for credit losses related to the loan and lease portfolio and unfunded lending commitments is reported in the Consolidated Statement of Income. For loans and leases, the ECL is typically estimated using quantitative methods that consider a variety of factors such as historical loss experience, the current credit quality of the portfolio as well as an economic outlook over the life of the loan. The life of the loan for closed-ended products is based on the contractual maturity of the loan adjusted for any expected prepayments. The contractual maturity includes any extension options that are at the sole discretion of the borrower. For open-ended products (e.g., lines of credit), the ECL is determined based on the maximum repayment term associated with future draws from credit lines unless those lines of credit are unconditionally cancellable (e.g., credit cards) in which case the Corporation does not record any allowance. In its loss forecasting framework, the Corporation incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios include variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to, unemployment rates, real estate prices, gross domestic product levels, corporate bond spreads and long-term interest rate forecasts. As any one economic outlook is inherently uncertain, the Corporation leverages multiple scenarios. The scenarios that are chosen each quarter and the amount of weighting given to each scenario depend on a variety of factors including recent economic events, leading economic indicators, views of internal as well as third-party economists and industry trends. The estimate of credit losses includes expected recoveries of amounts previously charged off (i.e., negative allowance). If a loan has been charged off, the expected cash flows on the loan are not limited by the current amortized cost balance. Instead, expected cash flows can be assumed up to the unpaid principal balance immediately prior to the charge-off. The allowance for loan and lease losses for troubled debt restructurings (TDR) is measured based on the present value of projected future lifetime principal and interest cash flows discounted at the loan’s original effective interest rate, or in cases where foreclosure is probable or the loan is collateral dependent, at the loan’s collateral value or its observable market price, if available. The measurement of ECL for the renegotiated consumer credit card TDR portfolio is based on the present value of projected cash flows discounted using the average TDR portfolio contractual interest rate, excluding promotionally priced loans, in effect prior to restructuring. Projected cash flows for TDRs use the same economic outlook as discussed above. For purposes of computing this specific loss component of the allowance, larger impaired loans are evaluated individually and smaller impaired loans are evaluated as a pool. Also included in the allowance for loan and lease losses are qualitative reserves to cover losses that are expected but, in the Corporation's assessment, may not be adequately represented in the quantitative methods or the economic assumptions described above. For example, factors that the Corporation considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and nonaccrual loans, the effect of external factors such as competition, and legal and regulatory requirements, among others. Further, the Corporation considers the inherent uncertainty in quantitative models that are built on historical data. With the exception of the Corporation's credit card portfolio, the Corporation does not include reserves for interest receivable in the measurement of the allowance for credit losses as the Corporation generally classifies consumer loans as nonperforming at 90 days past due and reverses interest income for these loans at that time. For credit card loans, the Corporation reserves for interest and fees as part of the allowance for loan and lease losses. Upon charge-off of a credit card loan, the Corporation reverses the interest and fee income against the income statement line item where it was originally recorded. The Corporation has identified the following three portfolio segments and measures the allowance for credit losses using the following methods. Consumer Real Estate To estimate ECL for consumer loans secured by residential real estate, the Corporation estimates the number of loans that will default over the life of the existing portfolio, after factoring in estimated prepayments, using quantitative modeling methodologies. The attributes that are most significant in estimating the Corporation’s ECL include refreshed loan-to-value (LTV) or, in the case of a subordinated lien, refreshed combined LTV (CLTV), borrower credit score, months since origination and geography, all of which are further broken down by present collection status (whether the loan is current, delinquent, in default, or in bankruptcy). The estimates are based on the Corporation’s historical experience with the loan portfolio, adjusted to reflect the economic outlook. The outlook on the unemployment rate and consumer real estate prices are key factors that impact the frequency and severity of loss estimates. The Corporation does not reserve for credit losses on the unpaid principal balance of loans insured by the Federal Housing Administration (FHA) and long-term standby loans, as these loans are fully insured. The Corporation records a reserve for unfunded lending commitments for the ECL associated with the undrawn portion of the Corporation’s HELOCs, which can only be canceled by the Corporation if certain criteria are met. The ECL associated with these unfunded lending commitments is calculated using the same models and methodologies noted above and incorporate utilization assumptions at time of default. For loans that are more than 180 days past due and collateral-dependent TDRs, the Corporation bases the allowance on the estimated fair value of the underlying collateral as of the reporting date less costs to sell. The fair value of the collateral securing these loans is generally determined using an automated valuation model (AVM) that estimates the value of a property by reference to market data including sales of comparable properties and price trends specific to the Metropolitan Statistical Area in which the property being valued is located. In the event that an AVM value is not available, the Corporation utilizes publicized indices or if these methods provide less reliable valuations, the Corporation uses appraisals or broker price opinions to estimate the fair value of the collateral. While there is inherent imprecision in these valuations, the Corporation believes that they are representative of this portfolio in the aggregate. For loans that are more than 180 days past due and collateral-dependent TDRs, with the exception of the Corporation’s fully insured portfolio, the outstanding balance of loans that is in excess of the estimated property value after adjusting for costs to sell is charged off. If the estimated property value decreases in periods subsequent to the initial charge-off, the Corporation will record an additional charge-off; however, if the value increases in periods subsequent to the charge-off, the Corporation will adjust the allowance to account for the increase but not to a level above the cumulative charge-off amount. Credit Cards and Other Consumer Credit cards are revolving lines of credit without a defined maturity date. The estimated life of a credit card receivable is determined by estimating the amount and timing of expected future payments (e.g., borrowers making full payments, minimum payments or somewhere in between) that it will take for a receivable balance to pay off. The ECL on the future payments incorporates the spending behavior of a borrower through time using key borrower-specific factors and the economic outlook described above. The Corporation applies all expected payments in accordance with the Credit Card Accountability Responsibility and Disclosure Act of 2009 (i.e., paying down the highest interest rate bucket first). Then forecasted future payments are prioritized to pay off the oldest balance until it is brought to zero or an expected charge-off amount. Unemployment rate outlook, borrower credit score, delinquency status and historical payment behavior are all key inputs into the credit card receivable loss forecasting model. Future draws on the credit card lines are excluded from the ECL as they are unconditionally cancellable. The ECL for the consumer vehicle lending portfolio is also determined using quantitative methods supplemented with qualitative analysis. The quantitative model estimates ECL giving consideration to key borrower and loan characteristics such as delinquency status, borrower credit score, LTV ratio, underlying collateral type and collateral value. Commercial The ECL on commercial loans is forecasted using models that estimate credit losses over the loan’s contractual life at an individual loan level. The models use the contractual terms to forecast future principal cash flows while also considering expected prepayments. For open-ended commitments such as revolving lines of credit, changes in funded balance are captured by forecasting a borrower’s draw and payment behavior over the remaining life of the commitment. For loans collateralized with commercial real estate and for which the underlying asset is the primary source of repayment, the loss forecasting models consider key loan and customer attributes such as LTV ratio, net operating income and debt service coverage, and captures variations in behavior according to property type and region. The commercial real estate model also utilizes key economic variables to forecast market indicators such as rent levels and vacancy rates, which impact the ECL estimate. For all other commercial loans and leases, the loss forecasting model determines the probabilities of transition to different credit risk ratings or default at each point over the life of the asset based on the borrower’s current credit risk rating, industry sector, size of the exposure and the geographic market. The severity of loss is determined based on the type of collateral securing the exposure, the size of the exposure, the borrower’s industry sector, any guarantors and the geographic market. Assumptions of expected loss are conditioned to the economic outlook and the model considers key economic variables such as unemployment rate, gross domestic product, credit risk spreads, asset prices and equity market returns. In addition to the allowance for loan and lease losses, the Corporation also estimates ECL related to unfunded lending commitments such as letters of credit, financial guarantees, unfunded bankers acceptances and binding loan commitments, excluding commitments accounted for under the fair value option. Reserves are estimated for the unfunded exposure using the same models and methodologies as the funded exposure and are reported as reserves for unfunded lending commitments. Securities The Corporation evaluates each available-for-sale (AFS) security where the value has declined below amortized cost. If the Corporation intends to sell or believes it is more likely than not that it will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities the Corporation intends to hold, the Corporation evaluates the debt securities for ECL except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality where the Corporation applies a zero credit loss assumption. For the remaining AFS debt securities, the Corporation considers qualitative parameters such as internal and external credit ratings and the value of underlying collateral. If an AFS debt security fails any of the qualitative parameters, a discounted cash flow analysis is used by the Corporation to determine if a portion of the unrealized loss is a result of a credit loss. Any credit losses determined are recognized as an increase to the allowance for credit losses through provision expense recorded in other income. Cash flows expected to be collected are estimated using all relevant information available such as, remaining payment terms, prepayment speeds, the financial condition of the issuer, expected defaults and the value of the underlying collateral. If any of the decline in fair value is related to market factors, that amount is recognized in accumulated other comprehensive income (OCI). In certain instances, the credit loss may exceed the total decline in fair value, in which case, the allowance recorded is limited to the difference between the amortized cost and the fair value of the asset. The Corporation separately evaluates its held-to-maturity (HTM) debt securities for any credit losses, of which substantially all qualify for the zero loss assumption. For the remaining securities, the Corporation performs a discounted cash flow analysis to estimate any credit losses which are then recognized as part of the allowance for credit losses. Other Assets For the Corporation’s financial assets that are measured at amortized cost and are not included in debt securities or loans and leases on the Consolidated Balance Sheet, the Corporation evaluates these assets for ECL using various techniques. For assets that are subject to collateral maintenance provisions, including federal funds sold and securities borrowed or purchased under agreements to resell, where the collateral consists of daily margining of liquid and marketable assets where the margining is expected to be maintained into the foreseeable future, the expected losses are assumed to be zero. For all other assets, the Corporation performs qualitative analyses, including consideration of historical losses and current economic conditions, to estimate any ECL which are then included in a valuation account that is recorded as a contra-asset against the amortized cost basis of the financial asset. Troubled Debt Restructurings The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of the COVID-19 pandemic. In accordance with the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), the Corporation has elected to not apply TDR classification to any COVID-19 related loan modifications that were performed after March 1, 2020 to borrowers who were current as of December 31, 2019. Accordingly, these restructurings are not classified as TDRs. In addition, for loans modified in response to the COVID-19 pandemic that do not meet the above criteria (e.g., current payment status at December 31, 2019), the Corporation is applying the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrowers' past due and nonaccrual status have not been impacted during the deferral period. The Corporation has continued to accrue interest during the deferral period using a constant effective yield method. For most mortgage, HELOC and commercial loan modifications, the contractual interest that accrued during the deferral period is payable at the maturity of the loan. The Corporation includes these amounts with the unpaid principal balance when computing its allowance for credit losses. Amounts that are subsequently deemed uncollectible are written off against the allowance for credit losses.

Line item totals are in the Consolidated Statement of Income and on the Consolidated Balance Sheet. (3) Amounts are recorded in interest income in the Consolidated Statement of Income.
Schedule of Derivative Instruments in Statement of Financial Position, Fair Value	The table below summarizes the carrying value of hedged assets and liabilities that are designated and qualifying in fair value hedging relationships along with the cumulative amount of fair value hedging adjustments included in the carrying value that have been recorded in the current hedging relationships. These fair value hedging adjustments are open basis adjustments that are not subject to amortization as long as the hedging relationship remains designated. Designated Fair Value Hedged Assets (Liabilities) September 30, 2020 December 31, 2019 (Dollars in millions) Carrying Value Cumulative Fair Value Adjustments (1) Carrying Value Cumulative Fair Value Adjustments (1) Long-term debt (2) $ (126,852) $ (12,071) $ (162,389) $ (8,685) Available-for-sale debt securities (2, 3, 4) 102,474 566 1,654 64 (1) For assets, increase (decrease) to carrying value and for liabilities, (increase) decrease to carrying value. (2) At September 30, 2020, the cumulative fair value adjustments remaining on long-term debt and AFS debt securities from discontinued hedging relationships resulted in an increase in the related liability of $1.3 billion and a decrease in the related asset of $6 million compared to a decrease in the related liability of $1.3 billion and an increase in the related asset of $8 million at December 31, 2019, which are being amortized over the remaining contractual life of the de-designated hedged items. (3) These amounts include the amortized cost basis of the prepayable financial assets used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. At September 30, 2020, the amortized cost of the closed portfolios used in these hedging relationships was $40.2 billion, of which $8.4 billion was designated in the hedging relationship. The cumulative basis adjustments associated with these hedging relationships totaled $33 million.
Cash Flow and Net Investment Hedges	The following table summarizes certain information related to cash flow hedges and net investment hedges for the three and nine months ended September 30, 2020 and 2019. Of the $408 million after-tax net gain ($542 million pretax) on derivatives in accumulated OCI at September 30, 2020, gains of $191 million after-tax ($252 million pretax) related to open cash flow hedges are expected to be reclassified into earnings in the next 12 months. These net gains reclassified into earnings are expected to primarily increase net interest income related to the respective hedged items. For terminated cash flow hedges, the time period over which the majority of the forecasted transactions are hedged is approximately 3 years, with a maximum length of time for certain forecasted transactions of 16 years. Gains and Losses on Derivatives Designated as Cash Flow and Net Investment Hedges Gains (Losses) Recognized in Gains (Losses) Gains (Losses) Recognized in Gains (Losses) (Dollars in millions, amounts pretax) Three Months Ended September 30, 2020 Nine Months Ended September 30, 2020 Cash flow hedges Interest rate risk on variable-rate assets (1) $ (101) $ 5 $ 810 $ (44) Price risk on forecasted MBS purchases (1) 184 3 184 3 Price risk on certain compensation plans (2) 32 5 23 5 Total $ 115 $ 13 $ 1,017 $ (36) Net investment hedges Foreign exchange risk (3) $ (703) $ — $ 265 $ 1 Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Cash flow hedges Interest rate risk on variable-rate assets (1) $ 125 $ (27) $ 743 $ (78) Net investment hedges Foreign exchange risk (3) $ 786 $ 362 $ 590 $ 363 (1) Amounts reclassified from accumulated OCI are recorded in interest income in the Consolidated Statement of Income.

Substantially all of these securities are classified as Level 2 within the fair value hierarchy and are typically sold shortly after receipt. (2) A majority of the first-lien residential mortgage loans securitized are initially classified as LHFS and accounted for under the fair value option. Gains recognized on these LHFS prior to securitization, which totaled $44 million and $105 million, net of hedges, during the three and nine months ended September 30, 2020 compared to $19 million and $38 million for the same periods in 2019, are not included in the table above. (3) The Corporation may have the option to repurchase delinquent loans out of securitization trusts, which reduces the amount of servicing advances it is required to make. The Corporation may also repurchase loans from securitization trusts to perform modifications. Repurchased loans include FHA-insured mortgages collateralizing GNMA securities.

Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables present a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three and nine months ended September 30, 2020 and 2019, including net realized and unrealized gains (losses) included in earnings and accumulated OCI. Transfers into Level 3 occur primarily due to decreased price observability, and transfers out of Level 3 occur primarily due to increased price observability. Transfers occur on a regular basis for long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole.
